Despite the caution, horseradish root has been tested and found effective for sinusitis and bronchitis, which are conditions that cause congestion. [15] X Research source Goos, K. H. , Albrecht, U. , and Schneider, B. [Efficacy and safety profile of a herbal drug containing nasturtium herb and horseradish root in acute sinusitis, acute bronchitis and acute urinary tract infection in comparison with other treatments in the daily practice/results of a prospective cohort study]. Arzneimittelforschung 2006;56(3):249-257 The common dosage for horseradish is 20 g of fresh root per day while you are suffering from congestion or respiratory issues.

The first time you try an herb, do so for only three to five minutes for steam treatments and and then wait for 30 minutes to determine if you are experiencing any adverse reactions. If you do, choose another herb. [17] X Research source
